Title:
Add WWAN framework and drivers support
Status in HWE Next:
New
Status in linux-intel package in Ubuntu:
Fix Committed
Bug description:
[SRU Justification]
[Impact]
The Quectel SDX24 EM160R-GL 4G LTE CAT16 PCIE Modem and Foxconn SDX55 T99W175
5G sub6 PCIE Modem are not supported in 5.11 kernel yet. The new WWAN framework
and driver support are required to be backported to detect and control the new
WWAN modules.
[Fix]
Backport the WWAN framework and drivers support from mainline kernel 5.13.
[Test Case]
Verify whether the Quectel/Foxconn WWAN module are detected or not. And use
either `mmcli` commands or NetworkSettings Panel to test the connection.
[Where problem could occur]
Since the WWAN framework is totally new which makes use of the existing MHI
bus drivers and protocols, it should be compatible with old WWAN modules. The
regression can be considered as low.
